23、or to cause tear failure of the upper or the sole is measured. It also defines conditions of ageing that can be used for production control. It applies to all types of footwear (cementing, vulcanisation, injection moulding, etc.) where the evaluation of sole adhesion on the upper is needed and where
24、 the upper is continuously assembled (closed shoe). NOTE 1In all cases the objective should be to test the bond strength nearest to the edge of the assembly. NOTE 2The test need not be carried out when the bond has been made by grindery (using, for example, nails or screws) or stitching. 2 Normative

The machine shall be fitted with either pincer or flat jaws (depending on the type of construction of the test sample), 25 mm to 30 mm
30、 wide, capable of firmly gripping the test pieces. A low-inertia machine having autographic force recording facilities is essential. 4.3 Vernier callipers For measuring of the width of the upper assembling margin or covering.

32、ber For each model, the minimum number of samples shall be two items of footwear. 5.3 Preparation of test pieces 5.3.1 Upper-sole adhesion: construction type a (see Figure 1) Take a test piece from either the inner or the outer joint region. Cut the test piece at X-X and Y-Y with sides at right angl
33、es to the edge of the sole using a press knife or bandsaw (see 4.1) to cut through the upper, innersole or outsole to produce a test piece about 25 mm wide. The length of the upper and sole shall be about 15 mm measured from the feather line (see Figure 2). Remove the insole. 5.3.2 Upper-sole adhesi
34、on: construction types b, c, d and e (see Figure 1) Take a test piece from either the inner or outer joint region. Cut the upper and sole at X-X and Y-Y to produce a test piece with a width of about 10 mm and a length of not less than 50 mm. Remove the insole. Separate the upper from the sole for a
35、length of about 10 mm by inserting a hot knife in the adhesive layer (see Figure 3). NOTEIt is considered that a construction is c or d when the distance from the X-X to the upper face of the insole is at least 8 mm. 5.3.3 Sole-interlayer adhesion: construction types f and g (see Figure 1) Take a te
36、st piece from either the inner or the outer joint region. Remove the upper by cutting along the feather line at X-X. Remove the insole if present. Cut a strip parallel to and including the sole edge at Y-Y to produce a test piece about 15 mm wide and at least 50 mm long. Separate the sole layers for
37、 a length of about 10 mm by inserting a hot knife into the adhesive layer (see Figure 3).

Clamp the test piece into the jaws of the tensile machine, using a pincer jaw to grip the short edge of th
43、e sole (see Figure 4), and record the force/deformation graph at a separation speed of 100 mm/min 20 mm/min.

48、, proceed differently. Note the strength after the unsticking of 10 mm and note the corresponding assembling margin. Then, calculate the local upper-sole adhesion, Ri. Calculate the average value of Ri. 7.2 Evaluation of appearance after the test The appearance of the separated areas (see 6.2.2.1 an
